Technical Interview Questions and Answers

1. Explain OOPs concepts with examples.

1. Encapsulation:

public class BankAccount {
    private double balance;  // Private data
    
    public void deposit(double amount) {  // Public methods
        if (amount > 0) balance += amount;
    }
    
    public double getBalance() {
        return balance;
    }
}

2. Inheritance:

class Vehicle {
    protected String brand;
    public void honk() { System.out.println("Beep!"); }
}

class Car extends Vehicle {
    private String model;
    public void display() {
        System.out.println(brand + " " + model);
    }
}

3. Polymorphism:

// Method Overriding (Runtime polymorphism)
class Animal {
    void makeSound() { System.out.println("Animal sound"); }
}

class Dog extends Animal {
    @Override
    void makeSound() { System.out.println("Bark"); }
}

// Method Overloading (Compile-time polymorphism)
class Calculator {
    int add(int a, int b) { return a + b; }
    double add(double a, double b) { return a + b; }
    int add(int a, int b, int c) { return a + b + c; }
}

4. Abstraction:

abstract class Shape {
    abstract double calculateArea();
    void display() { System.out.println("Displaying shape"); }
}

class Circle extends Shape {
    private double radius;
    
    Circle(double r) { this.radius = r; }
    
    @Override
    double calculateArea() {
        return Math.PI * radius * radius;
    }
}

---

2. Write a program to reverse a linked list.

Python Solution:

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

def reverse_linked_list(head):
    prev = None
    current = head
    
    while current:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    
    return prev

# Recursive solution
def reverse_recursive(head):
    if not head or not head.next:
        return head
    
    rest = reverse_recursive(head.next)
    head.next.next = head
    head.next = None
    
    return rest

# Print list
def print_list(head):
    while head:
        print(head.data, end=" -> ")
        head = head.next
    print("None")

# Test
head = Node(1)
head.next = Node(2)
head.next.next = Node(3)
head.next.next.next = Node(4)

print("Original:")
print_list(head)
head = reverse_linked_list(head)
print("Reversed:")
print_list(head)

Time Complexity: O(n) Space Complexity: O(1) iterative, O(n) recursive (call stack)

3. What is the difference between Abstract Class and Interface?

Feature	Abstract Class	Interface
Methods	Can have abstract and concrete methods	Only abstract methods (Java 7), default/static allowed (Java 8+)
Variables	Can have instance variables	Only public static final constants
Constructors	Can have constructors	No constructors
Multiple Inheritance	Not supported	Supported (a class can implement multiple interfaces)
Access Modifiers	Any access modifier	Methods are public by default
Use Case	'Is-a' relationship with shared code	'Can-do' relationship, defining contracts

When to use Abstract Class:

• Shared code among related classes
• Non-public members needed
• Need to define common state (fields)

When to use Interface:

• Defining contracts for unrelated classes
• Multiple inheritance needed
• API definition where implementation varies

Java 8+ Interface Features:

interface Drawable {
    void draw();  // Abstract method
    
    default void print() {  // Default method
        System.out.println("Printing...");
    }
    
    static void info() {  // Static method
        System.out.println("Drawable interface");
    }
}

4. Explain Database Normalization.

Database Normalization is the process of organizing data to minimize redundancy and dependency.

1NF (First Normal Form):

• All columns contain atomic (indivisible) values
• Each column contains values of a single type
• Each row is unique (primary key)

-- Before 1NF (phone numbers in single column)
| ID | Name  | Phone          |
|----|-------|----------------|
| 1  | John  | 1234, 5678     |

-- After 1NF
| ID | Name  | Phone   |
|----|-------|---------|
| 1  | John  | 1234    |
| 1  | John  | 5678    |

2NF (Second Normal Form):

• Must be in 1NF
• No partial dependency (non-key attributes depend on entire primary key)

-- Before 2NF
| StudentID | Subject  | StudentName | Marks |
|-----------|----------|-------------|-------|
| 1         | Math     | John        | 85    |

-- After 2NF (split into two tables)
Students: | StudentID | StudentName |
Marks:    | StudentID | Subject | Marks |

3NF (Third Normal Form):

• Must be in 2NF
• No transitive dependency (non-key attributes depend only on primary key)

-- Before 3NF
| EmpID | EmpName | DeptID | DeptName |
|-------|---------|--------|----------|
| 1     | John    | D1     | Sales    |

-- After 3NF
Employee: | EmpID | EmpName | DeptID |
Department: | DeptID | DeptName |

BCNF (Boyce-Codd Normal Form):

• Stricter version of 3NF
• Every determinant must be a candidate key

Denormalization: Sometimes intentionally used to improve read performance by accepting some redundancy.

5. Write a program to find duplicate characters in a string.

Python Solution:

def find_duplicates(s):
    char_count = {}
    
    for char in s:
        char_count[char] = char_count.get(char, 0) + 1
    
    duplicates = {char: count for char, count in char_count.items() if count > 1}
    return duplicates

# Alternative: Using collections.Counter
from collections import Counter

def find_duplicates_counter(s):
    counts = Counter(s)
    return {char: count for char, count in counts.items() if count > 1}

# Test
text = "programming"
result = find_duplicates(text)
print(f"Duplicates: {result}")  # {'r': 2, 'g': 2, 'm': 2}

Java Solution:

import java.util.*;

public class DuplicateCharacters {
    public static Map<Character, Integer> findDuplicates(String s) {
        Map<Character, Integer> charCount = new HashMap<>();
        Map<Character, Integer> duplicates = new HashMap<>();
        
        for (char c : s.toCharArray()) {
            charCount.put(c, charCount.getOrDefault(c, 0) + 1);
        }
        
        for (Map.Entry<Character, Integer> entry : charCount.entrySet()) {
            if (entry.getValue() > 1) {
                duplicates.put(entry.getKey(), entry.getValue());
            }
        }
        
        return duplicates;
    }
    
    public static void main(String[] args) {
        String text = "programming";
        Map<Character, Integer> result = findDuplicates(text);
        System.out.println("Duplicate characters: " + result);
    }
}

Time Complexity: O(n) Space Complexity: O(k) where k is the number of unique characters

6. Explain the difference between GET and POST methods.

Feature	GET	POST
Visibility	Data in URL (query string)	Data in request body
Caching	Can be cached	Not cached by default
Bookmark	Can be bookmarked	Cannot be bookmarked
Length	Limited by URL length (2048 chars)	No limitation
Security	Less secure (data in URL)	More secure (data in body)
Idempotent	Yes (same result for multiple calls)	No (may create multiple resources)
Use Case	Retrieving data	Creating/updating data
History	Stored in browser history	Not stored

GET Example:

GET /users?id=123 HTTP/1.1
Host: api.example.com

POST Example:

POST /users HTTP/1.1
Host: api.example.com
Content-Type: application/json

{
    "name": "John",
    "email": "[email protected]"
}

When to use GET:

• Safe operations (no side effects)
• Retrieving data
• Search queries
• Filtering/sorting

When to use POST:

• Creating new resources
• Operations with side effects
• Large data submissions
• Sensitive information

7. Write a program to check if a number is prime.

Optimized Python Solution:

import math

def is_prime(n):
    if n <= 1:
        return False
    if n <= 3:
        return True
    if n % 2 == 0 or n % 3 == 0:
        return False
    
    # Check for factors up to square root
    i = 5
    while i * i <= n:
        if n % i == 0 or n % (i + 2) == 0:
            return False
        i += 6
    
    return True

# Simpler version
def is_prime_simple(n):
    if n <= 1:
        return False
    for i in range(2, int(math.sqrt(n)) + 1):
        if n % i == 0:
            return False
    return True

# Test
print(is_prime(17))   # True
print(is_prime(18))   # False
print(is_prime(97))   # True

Time Complexity:

• Naive: O(n)
• Optimized (checking up to √n): O(√n)
• Highly optimized (6k ± 1): O(√n) with fewer iterations

8. What is the difference between HashMap and HashTable?

Feature	HashMap	Hashtable
Thread Safety	Not synchronized	Synchronized (thread-safe)
Performance	Faster (no synchronization overhead)	Slower due to synchronization
Null Keys/Values	Allows one null key, multiple null values	Does not allow null keys or values
Legacy	Java 1.2+ (part of Collections)	Legacy class (Java 1.0)
Iterator	Fail-fast iterator	Fail-fast enumerator
When to use	Single-threaded applications	Legacy code, thread-safe needs

Modern Alternative - ConcurrentHashMap:

// Better thread-safe alternative
import java.util.concurrent.ConcurrentHashMap;

Map<String, Integer> concurrentMap = new ConcurrentHashMap<>();

Example:

// HashMap
HashMap<String, String> hashMap = new HashMap<>();
hashMap.put(null, "value");  // OK
hashMap.put("key", null);    // OK

// Hashtable
Hashtable<String, String> hashtable = new Hashtable<>();
hashtable.put(null, "value");  // NullPointerException
hashtable.put("key", null);    // NullPointerException

Recommendation:

• Use HashMap for single-threaded applications
• Use ConcurrentHashMap for concurrent access
• Avoid Hashtable unless working with legacy APIs

9. Write a SQL query to find employees who earn more than their managers.

Table Structure:

CREATE TABLE Employee (
    id INT PRIMARY KEY,
    name VARCHAR(100),
    salary INT,
    manager_id INT,
    FOREIGN KEY (manager_id) REFERENCES Employee(id)
);

Solution:

SELECT e.name AS employee_name, e.salary AS employee_salary,
       m.name AS manager_name, m.salary AS manager_salary
FROM Employee e
JOIN Employee m ON e.manager_id = m.id
WHERE e.salary > m.salary;

Alternative with Subquery:

SELECT name, salary
FROM Employee
WHERE salary > (
    SELECT salary 
    FROM Employee 
    WHERE id = Employee.manager_id
);

Sample Data and Result:

-- Insert sample data
INSERT INTO Employee VALUES 
(1, 'Alice', 100000, NULL),    -- CEO
(2, 'Bob', 80000, 1),          -- Manager
(3, 'Charlie', 90000, 1),      -- Manager
(4, 'David', 85000, 2),        -- Employee (earns more than Bob!)
(5, 'Eve', 70000, 2);          -- Employee

-- Result: David earns more than manager Bob

My manager appreciated the proactive approach, and the guidelines became the standard for other teams. I learned that leadership is about taking initiative and delivering value, regardless of position.

---

4. Describe a time when you made a mistake at work or in a project.

Situation: During a college hackathon, I accidentally committed API keys to our public GitHub repository while pushing code minutes before the submission deadline.

Task: I needed to fix the security issue immediately while ensuring our project remained eligible for judging.

Action:

• Immediately revoked the exposed API keys from the provider's dashboard
• Generated new keys and configured them as environment variables
• Used git-filter-branch to remove the sensitive data from repository history
• Added .gitignore rules and documented the incident for the team
• Implemented pre-commit hooks to prevent future occurrences

Result: We resolved the issue within 15 minutes without disrupting the demo. The judges didn't notice any problems, and we placed in the top 5. This experience taught me the critical importance of security best practices and proper configuration management. Since then, I always use environment variables and never commit sensitive data.

---

5. Tell me about a time when you had to meet a tight deadline.

Situation: Two days before my final project submission, we discovered a critical bug in our application's payment flow that would cause transaction failures.

Task: I needed to identify and fix the bug while completing remaining documentation and preparing the presentation.

Action:

• Prioritized tasks: bug fix (critical), documentation (important), presentation enhancements (nice-to-have)
• Created a timeline with hourly milestones
• Set up comprehensive logging to trace the issue (found a race condition in async code)
• Implemented the fix and wrote unit tests to prevent regression
• Divided remaining documentation work among team members
• Took short breaks to maintain focus
